Description: TRICYCLIC DERIVATIVES AND THEIR USE IN PHARMACEUTICALS. FIELD OF THE INVENTION The present invention relates to tricyclic derivatives- pharmaceutical compositions and methods of using such derivatives. The compounds of the present invention inhibit tumor necrosis factor cc ("TNF-α"). BACKGROUND OF THE INVENTION Tumor necrosis factor α ("TNF-α") is a polypeptide cytokine known to induce a variety of inflammatory and metabolic processes in vivo. See, e.g., Ann. Rev. Immunol. 7:625 (1989). However, overproduction or inappropriate production of TNF-α has been shown to be involved in several pathological conditions, including septic shock and various allergic diseases and inflammatory conditions. See, e.g. , Immunol Res. 10:122 (1991), Science 229:869 (1985) and Proc. Natl. Acad. Sci. 89:7375 (1992). Thus, compounds that could inhibit TNF-α would be quite valuable in treating these conditions. In view of the substantial interest in agents that inhibit TNF-α, the identification of compounds having anti-TNF-α activity would be a valuable contribution to the art. This invention provides just such a contribution by providing novel compounds having anti- TNF-α activity. In addition, this invention provides methods of using such compounds. SUMMARY OF THE INVENTION We have now unexpectedly found that compounds having the general formula I (set forth below) provide surprisingly good activity as inhibitors of tumor necrosis factor α (TNF-α). More specifically, we believe that the compounds of formula I provide this activity by inhibiting the biosynthesis of TNF-α. In view of this surprising anti-TNF-α activity, it is believed that compounds of formula I are useful in the relief of septic shock, allergic diseases, and inflammatory conditions. Formula I is as follows: or a pharmaceutically acceptable salt or solvate thereof, wherein: one of T and U represents N and the other represents =CH-; or each of T and U represents =CH-; the line represents an optional double bond; when is a double bond, each of V and W represents =CH-; when represents a single bond, one of V and W represents oxygen and the other represents -CH2*; or each of V and W represents -CH2-; R 1 and R 2 are each independently selected from the group consisting of H and halogen; R 3 is H; alkyl; alkenyl; alkynyl; aryl; alkaryl; aralkyl; cycloalkyi; alkoxy; (CH 2 )nOR 10 ; (CH 2 )nCOOR 10 . wherein n is 1 to 3 and R 10 is H or lower alkyl; or S(0) e R 11 , wherein e is 0 or 2 and R 11 is alkyl or aryl; 3 - Q represents w herein one of J and K represents and the other represents -CH2-, with the proviso that when R 3 is H, Q is limited to either: or wherein J is -CH2-; R 1 2 is lower alkyl; R 16 is H; lower alkyl; aryl; aralkyi; alkaryl; COR 17 or C(0)OR 18 , wherein R 17 s H or lower alkyl or aryl, R 18 is lower alkyl or aryl; and X represents halogen. - 4 - More preferred compounds include those of Formula I wherein R 3 is alkyl. When R 3 is alkyl, R 3 is preferably an alkyl group other than -CH3, more preferably an alkyl group having from two to six carbon atoms, and more preferably still, R 3 is propyl. More preferred compounds also include those of Formula I wherein R 3 is alkeπyl, and more preferably wherein R 3 is allyl. More preferred compounds also include those of Formula I wherein each of T and U represents =CH-. Furthermore, preferred compounds also include those of Formula I wherein Q is: or wherein R 16 is H, lower alkyl, aryl, aralkyi or alkaryl.

In addition, this invention provides a method for inhibiting TNF-α in a mammal comprising administering to the mammal an amount of a compound of Formula I effective to inhibit TNF-α. In view of the surprising anti-TNF-α activity of compounds of formula I, this invention provides the following methods of treatment: - a method for treating inflammation in a mammal comprising administering to the mammal an effective anti- inflammatory amount of a compound of Formula I; - a method for treating septic shock in a mammal comprising administering to the mammal an effective anti-septic shock amount of a compound of Formula I; and - a method for treating allergic reaction in a mammal comprising administering to the mammal an effective anti-allergic amount of a compound of Formula I. It also has been surprisingly found that the following known compound (hereafter referred to as Compound K) has anti-TNF- α activity: (K) 10 Heretofore, Compound K was only disclosed as having cardiovascular activity. (See King et al, U.S. Patent 4,626,542). Accordingly, the present invention also provides a method for inhibiting TNF-α in a mammal comprising administering to the mammal an amount of Compound K effective to inhibit TNF-α. In view of the surprising anti-TNF activity of Compound K, this invention also provides the following methods of treatment: - a method for treating inflammation in a mammal comprising administering to the mammal an effective anti- inflammatory amount of Compound K; - a method for treating septic shock in a mammal comprising administering to the mammal an effective anti-septic shock amount of Compound K; and - a method for treating allergic reaction in a mammal comprising administering to the mammal an effective anti-allergic amount of Compound K.

Certain compounds of the invention may exist in different isomeric (e.g., enantiomers and diastereoisomers) as well as conformational forms. The invention contemplates all such isomers 12 both in pure form and in admixture, including racemic mixtures. Tautomeric forms are also included. The compounds of Formula I can exist in unsolvated as well as solvated forms, including hydrated forms, e.g., hemi-hydrate. In general, the solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like are equivalent to the unsolvated forms for purposes of the invention. Lines drawn into the ring systems indicate that the indicated bond may be attached to any of the substitutable ring carbon atoms. Certain compounds of the invention will be acidic in nature, e.g. those compounds which possess a carboxyl or phenolic hydroxyl group. These compounds may form pharmaceutically acceptable salts. Examples of such salts may include sodium, potassium, calcium, aluminum, gold and silver salts. Also contemplated are salts formed with pharmaceutically acceptable amines such as ammonia, alkyl amines, hydroxyalkylamines, N-methylglucamine and the like. Certain basic compounds of the invention also form pharmaceutically acceptable salts, e.g., acid addition salts. For example, the pyrido-nitrogen atoms may form salts with strong acid, while compounds having basic substituents such as amino groups also form salts with weaker acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those skilled in the art. The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt in the conventional manner. The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium hydroxide, potassium carbonate, ammonia and sodium bicarbonate. The free base forms differ from their respective salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the acid and base - 13 - salts are otherwise equivalent to their respective free base forms for purposes of the invention. All such acid and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention. The invention disclosed herein is exemplified by the following preparative examples, which should not be construed to limit the scope of the disclosure. Alternative synthetic pathways and analogous structures within the scope of the invention may be apparent to those of ordinary skill in the art. Further, those skilled in the art will recognize that the reactions are conducted under conditions, e.g., temperature, that will allow the reaction to proceed at a reasonable rate to completion. Unless indicated otherwise, the substituents for the formulas given hereinafter have the same definition as those of Formula I. - 14 PREPARATIVE METHODS AND REACTION SCHEMES Scheme 1: - 15 Step 1: This step is preferably carried out by adding the grigπard reagent of 4-chloro-N-methyl-piperidine in an inert solvent such as ether (e.g. diethyl ether, tetrahydrofuran, or dioxane) under an inert atmosphere (nitrogen or argon).
